Drop analyticsNameOverride on app generate extension

[alfonso-noriega]

WHY are these changes introduced?

Addresses this metric thread on #7524. The app generate extension command currently overrides its analytics name to app scaffold extension — a holdover from before the rename. Now that the deprecated scaffold extension command itself is being removed in the parent PR (#7525), this override is misleading: analytics events from app generate extension should report the actual command name users run.

Stacked on top of #7525.

WHAT is this pull request doing?

• Removes the analyticsNameOverride() method from AppGenerateExtension.
• Analytics events for shopify app generate extension will now flow through with the natural command name (app generate extension) instead of the legacy app scaffold extension.

How to test your changes?

1. Run pnpm shopify app generate extension --template ... in dev mode.
2. Confirm the analytics event reports app generate extension (e.g. via debug analytics output) — not app scaffold extension.

Checklist

• I've considered possible cross-platform impacts (Mac, Linux, Windows)
• I've considered possible documentation changes
• I've considered analytics changes to measure impact — this PR is the analytics change
• No user-visible behaviour change → no changeset

Differences in type declarations

We detected differences in the type declarations generated by Typescript for this branch compared to the baseline ('main' branch). Please, review them to ensure they are backward-compatible. Here are some important things to keep in mind:

• Some seemingly private modules might be re-exported through public modules.
• If the branch is behind main you might see odd diffs, rebase main into this branch.
